The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the collapsible internal-external hexagon combination wrenches of the utility model comprises mobile jib 2, inner hexagon spanner 3, outer hexagonal spanner 5, mobile jib 2 cross sections are regular hexagon, and mobile jib 2 one ends are connected with inner hexagon spanner 3 vertically, and bottom surface, the other end offers transverse concave groove 7; Outer hexagonal spanner 5 connecting rod tail ends are positioned at transverse concave groove 7 and by bearing pin 1 and mobile jib 2, are flexibly connected, and bearing pin 1 axis is vertical with mobile jib 2 axis, realize that take bearing pin 1 axis as rotating shaft 0 ° ~ 180 ° of outer hexagonal spanner 5 rotate freely; On outer hexagonal spanner 3 connecting rods, positioning bead 4 is set; Transverse concave groove 7 is along opening a locating hole 8 on the cell wall of mobile jib 2 axis directions; When outer hexagonal spanner 5 anglecs of rotation are 90 °, its axis and inner hexagon spanner 3 connecting rods and mobile jib 2 axis are straight line, and positioning bead 4 is overlapping with locating hole 8, and positioning bead 4 sticks into the interior realization of locating hole 8 location automatically; When outer hexagonal spanner 5 anglecs of rotation are 0 °, its axis is vertical with inner hexagon spanner 3 connecting rods and mobile jib 2 axis; Be provided with the unlock button 6 affixed with mobile jib 2 in locating hole 8, it comprises ball button 61, spring 62 and the slide block 63 that is connected successively, as shown in Figure 6, ball button 61 slightly protrudes from locating hole 8, by release and the location of pressing and the ball button 61 that resets is realized positioning bead 4.
The utility model is divided into folding and non-folding two kinds of duties.
Folded state: namely outer hexagonal spanner 5 anglecs of rotation are 90 °, as shown in Figure 4, its axis and inner hexagon spanner 3 connecting rods and mobile jib 2 axis are straight line, and positioning bead 4 is lucky and locating hole 8 is overlapping, positioning bead 4 sticks into the interior realization of locating hole 8 location automatically, and outer hexagonal spanner 5 is in non-rotatable state, this moment the spanner minimum that takes up room, being adapted to has the limited situations in operating space such as other objects block around bolt, and using method is with the normal screws cutter.
Non-folded state: namely outer hexagonal spanner 5 anglecs of rotation are non-90 °, and are special, when the anglec of rotation is 0 ° or 180 °, as shown in Figure 1, Figure 2 and Figure 3, its axis is vertical with inner hexagon spanner 3 connecting rods and mobile jib 2 axis, and this moment, the arm of force was maximum, can provide maximum moment of torsion to be used for elasticity bolt.
Switch to non-folded state from folded state, press ball button 61, spring 62 compresses and promotes slide block 63 tops to positioning bead 4, makes it break away from locating hole 8 and reaches the release purpose, and outer hexagonal spanner 5 is in rotatable state; The ball button 61 that resets namely recovers the positioning states of positioning bead 4 again.
The utility model integrates inside/outside die nut function, and moment of torsion is adjustable, and is simple to operate, not only be adapted to need larger rotating torque the operation of bolt degree of tightness, also be adapted to the bolt degree of tightness that other objects block while waiting space to be restricted and operate.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
